DETAILED DESCRIPTION OF THE INVENTION

A robust antibody response is essential for efficient identification and eradication of pathogenic microbes and toxins, whereas dysregulation of the antibody response can lead to autoimmune disease. Specific antigen encounter by B lymphocytes induces clonal expansion that encompasses several distinct stages of differentiation. During this differentiation process, a critical cell fate decision is made wherein some B cells will undergo terminal differentiation into antibody-producing cells, while a separate cohort will assume a distinct pathway of differentiation to become long-lived memory B cells.

EBI2 is expressed on B cells and is highly induced upon activation. EBI2 was cloned in 1993 as one out of nine up-regulated genes in Epstein-Barr virus (EBV)-infected Burkitt lymphoma cells. These nine genes were up-regulated from 4- to 100-fold upon EBV infection, and two 7TM receptors were identified among the up-regulated genes (Epstein-Barr-induced receptors 1 and 2, EBI1 and -2). EBI2 displayed the highest up-regulation (200-fold) among the nine EBV-induced genes. Initial expression analyses of the nine genes uncovered an expression of EBI2 in peripheral blood mononuclear cells (PBMCs), tonsils, spleen, and lung tissue.

EBI2 has been characterized in terms of signaling activities at the level of G-proteins as well as at the level of the transcriptional activity. Recent gene targeting experiments revealed that EBI2−/− B cells exhibited defective migration, resulting in strongly impaired T cell-dependent antibody responses.

The role of EBI2 in diseases involving an immune system dysregulation or diseases involving EBV infection is compelling. Many of these diseases overlap, as, in addition to EBI2, EBV regulates many different proteins related to the immune system, such as chemokines and their receptors. There are many disorders in which immune dysregulation have been implicated. Autoimmune and autoinflammatory disorders, such as type-1-diabetes, multiple sclerosis, rheumatoid arthritis, and systemic lupus erythematosus, have been connected to an aberrant activation of the immune system.

Inflammation substantially contributes to the pathophysiology of cardiovascular disease, and especially of atherosclerosis. As high levels of oxysterols (physiologic ligands for EBI2) are present in an atherosclerotic plaque and EBI2 is expressed on monocytes, which have a central role in atherosclerosis, the oxysterol-EBI2 pathway may be involved in the recruitment of immune cells to atherosclerotic lesions. Thus, EBI2 blockade might provide a therapeutic benefit in atherosclerosis.

In some embodiments, the compounds described herein are EBI2 antagonists.

In some embodiments, the compounds described herein are EBI2 inverse agonists.

Further Forms of Compounds

In one aspect, the compound of Formula (I), (II), (III), (IV), (V), (VI), (VII), or (VIII), possesses one or more stereocenters and each stereocenter exists independently in either the R or S configuration. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. The compounds and methods provided herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. In certain embodiments, compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds/salts, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, resolution of enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein. In another embodiment, diastereomers are seprated by separation/resolution techniques based upon differences in solubility. In other embodiments, separation of steroisomers is performed by chromatography or by the forming diastereomeric salts and separation by recrystallization, or chromatography, or any combination thereof. Jean Jacques, Andre Collet, Samuel H. Wilen, “Enantiomers, Racemates and Resolutions”, John Wiley And Sons, Inc., 1981. In one aspect, stereoisomers are obtained by stereoselective synthesis.

In some embodiments, compounds described herein are prepared as prodrugs. A “prodrug” refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. An example, without limitation, of a prodrug is a compound described herein, which is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound.

In one aspect, prodrugs are designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacokinetic, pharmacodynamic processes and drug metabolism in vivo, once a pharmaceutically active compound is known, the design prodrugs of the compound is possible. (see, for example, Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Rooseboom et al., Pharmacological Reviews, 56:53-102, 2004; Aesop Cho, “Recent Advances in Oral Prodrug Discovery”, Annual Reports in Medicinal Chemistry, Vol. 41, 395-407, 2006; T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series).

In some cases, some of the herein-described compounds may be a prodrug for another derivative or active compound.

In some embodiments, sites on the aromatic ring portion of compounds described herein are susceptible to various metabolic reactions Therefore incorporation of appropriate substituents on the aromatic ring structures will reduce, minimize or eliminate this metabolic pathway. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, or an alkyl group.

In another embodiment, the compounds described herein are labeled isotopically (e.g. with a radioisotope) or by another other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels.

Compounds described herein include isotopically-labeled compounds, which are identical to those recited in the various formulae and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, sulfur, fluorine and chlorine, such as, for example, ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F, ³⁶Cl. In one aspect, isotopically-labeled compounds described herein, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. In one aspect, substitution with isotopes such as deuterium affords certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements.

In additional or further embodiments, the compounds described herein are metabolized upon administration to an organism in need to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect.

“Pharmaceutically acceptable” as used herein, refers a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compound, and is relatively nontoxic, i.e., the material may be administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained.

The term “pharmaceutically acceptable salt” refers to a formulation of a compound that does not cause significant irritation to an organism to which it is administered and does not abrogate the biological activity and properties of the compound. In some embodiments, pharmaceutically acceptable salts are obtained by reacting a compound of Formula (I), (II), (III), (IV), (V), (VI), (VII), or (VIII) with acids. Pharmaceutically acceptable salts are also obtained by reacting a compound of Formula (I), (II), (III), (IV), (V), (VI), (VII), or (VIII) with a base to form a salt.

Compounds described herein may be formed as, and/or used as, pharmaceutically acceptable salts. The type of pharmaceutical acceptable salts, include, but are not limited to: (1) acid addition salts, formed by reacting the free base form of the compound with a pharmaceutically acceptable: inorganic acid, such as, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, metaphosphoric acid, and the like; or with an organic acid, such as, for example, acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, trifluoroacetic acid, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, toluenesulfonic acid, 2-naphthalenesulfonic acid, 4-methylbicyclo-[2.2.2]oct-2-ene-1-carboxylic acid, glucoheptonic acid, 4,4′-methylenebis-(3-hydroxy-2-ene-1-carboxylic acid), 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid, muconic acid, butyric acid, phenylacetic acid, phenylbutyric acid, valproic acid, and the like; (2) salts formed when an acidic proton present in the parent compound is replaced by a metal ion, e.g., an alkali metal ion (e.g. lithium, sodium, potassium), an alkaline earth ion (e.g. magnesium, or calcium), or an aluminum ion. In some cases, compounds described herein may coordinate with an organic base, such as, but not limited to, ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, dicyclohexylamine, tris(hydroxymethyl)methylamine. In other cases, compounds described herein may form salts with amino acids such as, but not limited to, arginine, lysine, and the like. Acceptable inorganic bases used to form salts with compounds that include an acidic proton, include, but are not limited to, aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, sodium hydroxide, and the like.
